years,  and having  a   whole   series  of  supposedly  forgotten   incidents   or  events
connected   with    our former  associations    flood   into    the mind.   Things  we  did,
topics  we  discussed,  trips   we  took,   games   we  played, now recur   at  the renewal of
our  acquaintance.   For     these   are     the     things  that    were    contiguous  in  our
consciousness   with    our sense   of  the personality and appearance  of  our friend.
And who has not in  similar fashion had a   whiff   of  perfume or  the strains of  a
song    recall  to  him his childhood   days!   Contiguity  is  again   the explanation.
At  the Mercy   of  Our Associations.—Through   the law thus    operating   we  are in
a   sense   at  the mercy   of  our associations,   which   may be  bad as  well    as  good.   We
may form    certain lines   of  interest    to  guide   our thought,    and attention   may in
some    degree  direct  it, but one's   mental  make-up is, after   all,    largely dependent   on
the character   of  his associations.   Evil    thoughts,   evil    memories,   evil    imaginations
—these  all come    about   through the association of  unworthy    or  impure  images
along   with    the good    in  our stream  of  thought.    We  may try to  forget  the base    deed
and banish  it  forever from    our thinking,   but lo! in  an  unguarded   moment  the
nerve   current shoots  into    the old path,   and the impure  thought flashes into    the
mind,   unsought    and unwelcomed. Every   young   man who thinks  he  must    indulge
in  a   little  sowing  of  wild    oats    before  he  settles down    to  a   correct life,   and so
deals   in  unworthy    thoughts    and deeds,  is  putting a   mortgage    on  his future; for he
will    find    the inexorable  machinery   of  his nervous system  grinding    the hated
images  of  such    things  back    into    his mind    as  surely  as  the mill    returns to  the sack
of  the miller  what    he  feeds   into    the hopper. He  may refuse  to  harbor  these
thoughts,   but he  can no  more    hinder  their   seeking admission   to  his mind    than    he
can prevent the tramp   from    knocking    at  his door.   He  may drive   such    images
from    his mind    the moment  they    are discovered, and indeed  is  guilty  if  he  does
not;    but not taking  offense at  this    rebuff, the unwelcome   thought again   seeks
admission.
The  only    protection  against     the     return  of  the     undesirable     associations    is  to
choose  lines   of  thought as  little  related to  them    as  possible.   But even    then,   do  the
best    we  may,    an  occasional  "connection"    will    be  set up, we  know    not how,    and
the unwelcome   image   stands  staring us  in  the face,   as  the corpse  of  Eugene
Aram's  victim  confronted  him at  every   turn,   though  he  thought it  safely  buried.
A   minister    of  my  acquaintance    tells   me  that    in  the holiest moments of  his most
exalted thought,    images  rise    in  his mind    which   he  loathes,    and from    which   he
recoils in  horror. Not only    does    he  drive   them    away    at  once,   but he  seeks   to  lock
and bar the door    against them    by  firmly  resolving   that    he  will    never   think   of
them    again.  But alas!   that    is  beyond  his control.    The tares   have    been    sown
